Serial No. 539,169.

This invention relates to pie making machines and a matrix therefor,also to a new process for lining multi-unit pie molds. The machine andmatrix are particularly adapted for use in the process of making diestamped or molded sector shaped individual sealed ies. p One object ofthis invention is the quick lining of a pie mold.

Another 'object is to reduce the cost of manufacturing stamped or moldedsector shaped individual sealed pies.

Another object is the production of a better sector shaped individualsealed pie.

Other obj ects will appear from the detailed description which follows.

In the drawings comprising two sheets of 10 figures numbered Figures 1to 10 inclusive, one embodiment of the apparatus is set forth.

Like reference characters designate corresponding parts throughout theseveral figures of the drawings.

The apparatus consists essentially of a matrix for pressing the lowerlayer of dough into the sector shaped receptacles of a multi unit moldto line the same; and a work bench or table for supporting the mold,having mechanism for bringing the matrix and mold into correct registryto eifect said dough lining operation.

The table may consist of a plurality of supports 20-21 strengthened bymeans of a suitable cross piece 22 and carrying a table or bench top 23.A suitable bracket 24 is secured to said table top by suitable screws-or rivets 25-25. Arm 30 of the bracket 24 may be further re-enforced bysuitable re-enforcing members 26-28 whichk are secured to the table bysuitable screws or rivets 27-29. An extension arm 31 is secured tobracket 24 in spaced parallel relationwitli respect to the arm 30, andthe arms 30 and 31 are further braced by means of the cross piece 32.The bracket 24 is extended by means of the extension arm 33 whichpivotally supports the lever arm 34 at 35. A lever 40 having a foot rest41 is pivotally supported by the table as at 39 and levers 34 and 40 arepivotally interconnected at'36 and 38 by means of a connecting rod 37 sothat whenever lever 40 is depressed by the application of foot pressureto foot rest 41 that arm of lever 34 which is pivotally secured toconnecting rod 37 moves upwards and the other arm of lever 34 movesdownwards.

The matrix stem 46 is slidably mounted in arms 30 and 3l and is providedwith an eye 43 at its upper end to permit the insertion of lever arm 34therein to translate the swinging movement of the lever into thedownward thrust of matrix stern 46. A roller mounted on a spindle 54supports lever arm 34 within the eye 43. A collar 56 is secured to thematrix stem 46 by means of pin 63. Mounted upon the matrix stem 46between arm 30 and collar 56 is a coiled spring 45 tending to retain thematrix stem in its upper (normal) position.

The matrix stem 46 is partially flattened at 57 throughout a portion ofits length (compare Figures 8 and 10) thereby forming centering meanswhich co-acts with the plate 58 to prevent improper adjustment of thematrix stem. Plate 58 is adjustably secured to arm 31 by means of setscrew 59.

The matrix 47 is secured to the collar 60 of matrix stem 46 by means ofsuitable screws 61. This matrix is shaped to conform to the shape andinternal configuration of the lower mold or pie pan 49 which may be ofany preferred form or size but which is preferablydcircular in shape toconform to the conventional pie pan. Mold 49 is subdivided into aplurality of sector shaped' recesses 5252 as indicated in Figures 5 and6 and matrix 47 is provided with a plurality of elements 48-48conforming in shape and substantially conforming in size to the recesses52 in the mold 49, the elements 48 being slightly smaller in size thanthe recess 52. the ditl'erence in size being substantially equal to theultimate thickness of the layer ot dough 53 (Figure 6), so that wheneverthe elements 48 of matrix 47 are brought into correct registry with therecesses 52 of the mold 49 the lower layer of dough 53 will be snuglypressed against the walls of the recesses 52 to form a lining for, andfaithfully conforming to the shape of, the recessed mold.

To facilitate the correct positioning of the interchangeable mold 49with respect to the matrix 47 'so as to permit the elements 48 of thematrix 47 to correctly register with the receptacles 52 of the mold 49centering means is provided which may consists of a plurality ofprojecting ribs 50-51 disposed at a suitable angle (for example, rightangles) to each other. These ribs are secured to the surface of thetable top 23 and are arran ed to intersect at a point perpendicularlyeneath the central point of the matrix 47. The ribs 50 and 51 are shapedto snugly fill the channels 62 formed between the undersides of theradial walls of the sector shaped receptacles 52 of the interchangeablemold 49 so that when said mold is placed upon the table in such aposition that its intersecting channels 62 register with theintersecting ribs 50 and 51 it will be in a correct position to registerwith the elements 48 of the matrix 47 when the latter descends undercontrol of the matrix stem 46.

The method of operation is as follows:

After the operator has covered one of the interchangeable molds 49 witha sheet of dough the mold is quickly placed upon the table in positionto permit the intersecting ribs 50 and 51 to register with theintersecting channels 62 upon the underside of the mold. The operatornow applies foot pressure to the foot pedal 41 causing lever 40 to swingabout its pivot 39 thereupon causing connecting rod 37 to move in anupward direction and swing lever 34 about its pivot End 44 of lever 34swings in a downward di rection forcing the matrix stem 46 downwardsagainst the ever increasing tension of the coiled spring 45. Matrix 47carried by stem 46 likewise moves downwards until the several elements48 register within the several recesses 52 of mold 49 pressing the dough53 against the 4walls of the mold until the dough assumes theconfiguration of the mold and lines the walls thereof to constitute ineffect the foundation or lower layer of dough of thc partially formedpie. Upon removing pressure from foot pedal 41, coiled spring 45 forcesthe matrix stem 46 upwards until the shoulder of collar 60 abuts againstthe underside of arm 31 preventing further upward movement of stem 46and restoring the machine to normal.

The dough 53 may thus be very quickly and accurately positioned in themold and as the entire operation is completed instantaneously much timeand labor is saved so that the operator is able to make pies much morerapidly than would be the case if it was necessary for him to performthe operation manually, whereby the production cost of die stamped ormolded sector shaped individual sealed pies is very materially reduced,and this saving can in turn be passed onto the customer.

By the use of a matrix in this manner the pies when formed will beuniform in appearance and attractive to the buyer.

Obviously the form of the lever mechanism employed to operate the matrixcan be modified in many ways without departing from the spirit of theinvention.
